feat: Enable verbose logging in port-agent configuration

[Amichai-Skaliter-Port]

Description

What - Added VERBOSE_LOGGING environment variable configuration to the Port Agent Helm chart to allow users to control logging verbosity.
Why - To provide users with the ability to disable verbose logging of message bodies, request/response payloads, and API responses for enhanced security and compliance requirements, while maintaining backwards compatibility with the current logging behavior.

How - Added VERBOSE_LOGGING: "true" to the env.normal section in charts/port-agent/values.yaml

• The variable is automatically injected into the deployment via the existing port-agent.envVariables helper template
• Default value is "true" to maintain current verbose logging behavior (backwards compatible)
• Users can override to "false" in their custom values to enable metadata-only logging
